Abstract

The drilling tool for the arc-shaped machining face of the aero-engine part comprises a positioning sleeve, and the front end of the positioning sleeve makes contact with the arc-shaped machining face so that the position to be drilled on the arc-shaped machining face can be primarily positioned. A drilling structure is inserted into the tail end of the positioning sleeve, a drill bit of the drilling structure is located in the positioning sleeve, and the drill bit corresponds to the position to be drilled on the arc-shaped machining face under the guidance of the positioning sleeve. The drilling tool designed by the invention can ensure the quality of a positioning hole or a mounting hole in an arc-shaped machining surface of a part, so that the quality, the service life and the machining efficiency of the part are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aero-engine parts processing, relates to a drilling technology for the processing surfaces of the parts, especially the arc-shaped processing surfaces, and in particular relates to a drilling tool for the arc-shaped processing surfaces of the aero-engine parts. Background technique [0002] During the processing of product parts, it is usually necessary to process positioning holes or mounting holes on different processing surfaces for positioning or assembling between various parts. One, and its processing surface is an arc surface, it is necessary to process rivet holes on the arc surface to connect the parts. [0003] At present, the rivet holes on the curved surface of the large thrust reverser are drilled directly with a hand electric drill. During the drilling process, there are problems such as oblique holes, large holes, and oval holes. Large gaps, rework and repairs affect the quality and life o...
